Diagnostic Notes

Halictus chapmani Cockerell, 1910b: 273.
Lasioglossum (Chilalictus) chapmani. Michener, 1965: 175.

Halictus chapmani Cockerell, T.D.A. 1910. Descriptions and records of bees. XXXII. Annals and Magazine of Natural History 8 6: 272–284 [273].

Type data: Holotype ZMB 2564 ?, WA.

Diagnosis. Most like L. expansifrons. Both sexes with body black. Female with head triangular in shape, frons coarsely reticulate/striate, pronotal dorsolateral angles acute, mesoscutum densely punctate, surface shining, dorsal surface of propodeum weakly defined posterolaterally by carinae, dorsal sculpture ruguloso-striolate. Male with antennae moderately long, face covered with dense hair, S2-S4 with long plumose posteriorly directed hair in rows across sterna; forewings with 2nd r-m as strong as 1st r-m.

Remarks. Female specimens of L. chapmani and L. expansifrons are similar, although separated by characters noted in the key (couplet 188). In addition, the male ventral metasomal pubescence and genitalia are strikingly different.
